| titleOfInvention | Neutral aluminum salt sizing precipitator and preparation method and application thereof |
| abstract | The invention discloses a neutral aluminum salt sizing precipitant, a preparation method and an application thereof, wherein the preparation method comprises the following steps: s1, changing AlCl 3 Adding an aluminum source into the solution, stirring at the temperature of 80-100 ℃ until the aluminum is completely dissolved, and filtering to obtain a first solution; s2, diluting the first solution to enable C2Al T ]Has a value of 0.03 to 0.05mol/L, and Al is added 3+ Adjusting the pH value to 4.5-5.5 by using an organic coordination stabilizer to obtain a second solution; s3, adding an organic pH regulator into the second solution to regulate the pH to 7.0-8.0 to obtain a third solution; and S4, evaporating water in the third solution, performing suction filtration to obtain crystals, and drying the crystals to obtain the sizing precipitant. The disclosure also provides a neutral aluminum salt sizing precipitant prepared by the method and application thereof. The prepared neutral aluminum salt sizing precipitator and gelatin are mixed and sized to form a reticular complex, so that the crosslinking of the gelatin is enhanced, the water resistance and the mechanical strength of paper are improved, and the coloring and color fixing effects of the pigment are good. |
